Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a nozzle rocking device of a sanitary washing device that ejects washing water for a toilet with a sanitary washer.

[0002]

[Prior art]

 The nozzle swing device of the conventional sanitary washing device that spouts washing water in a toilet with a sanitary washer is composed of a nozzle outer cylinder and a nozzle pipe, etc., and the washing water jetting position is fixed at a certain position during anus washing. Was there. However, the direction of the nozzle outer cylinder, which has been advanced in accordance with the body shape of the human body used in recent years, can be changed three-dimensionally by controlling two motors, a vertical movement motor and a horizontal movement motor, to freely change the direction of jetting of cleaning water. There is an example (for example, Japanese Utility Model Laid-Open No. 62-89376).

[0003]

[Problems to be solved by the device]

 In the latter example of the related art, it is possible to freely change the jetting direction of the washing water according to the body shape of the human body to be used, so that comfortable washing can be performed. However, since the posture of the nozzle outer cylinder controls two motors, a vertical movement motor and a horizontal movement motor, the mechanism is complicated and expensive.

[0004]

[Means for Solving the Problems]

 The present invention has been made in order to solve the above-mentioned problems, and a nozzle outer cylinder for accommodating a nozzle pipe having a nozzle at its tip and for moving the nozzle pipe forward and backward between the accommodating position and the cleaning position is provided. In a nozzle swinging device of a sanitary washing device provided with an engaging pin protruding from an outer cylinder of a nozzle, a cam roller provided with a meandering groove that movably engages with the engaging pin and meanders back and forth and left and right, and An outer cylinder holding plate that pivotally supports the cam roller and movably holds the nozzle outer cylinder, an elastic member bridged between the outer cylinder holding plate and the nozzle outer cylinder, and the cam roller installed on the outer cylinder holding plate. It is composed of a small motor that drives the.

[0005]

[Action]

 With the above configuration, when the cam roller is driven to rotate, the engagement pin of the nozzle outer cylinder swings back and forth and left and right following the meandering groove of the cam roller. Further, the elastic member laid between the outer cylinder holding plate and the nozzle outer cylinder is elastically displaced in association with the engaging pin of the nozzle outer cylinder. For this reason, the nozzle pipe oscillates around the cam roller as a fulcrum as shown by arrows C-D (horizontal movement) and AB (forward / backward movement) shown in FIGS. 1 and 2, and as a result, the cleaning water is ejected from the ejection port. The position swings b to the left and right and a to the front and back.

Therefore, it is possible to change the jet direction of the washing water over a wide range according to the body shape of the human body to be used.

[0007]

【Example】

 An embodiment of the present invention will be described with reference to FIGS.

In the drawing, reference numeral 1 is a nozzle outer cylinder, and 2-2 is an engaging pin for swinging, which is provided so as to project slightly to the tip end side from the central portion of the nozzle outer cylinder 1. Reference numeral 3 is a cam roller having a shaft hole 3a, and a meandering groove 3b for rocking which is meandering back and forth and left and right is provided around the outer peripheral portion, and the engaging pin 2-2 of the nozzle outer cylinder 1 is movably mounted on the upper surface of the meandering groove 3b. Engaged. A small motor 4 drives the cam roller 3 to rotate.

Reference numeral 5 denotes a cylindrical outer cylinder holding plate, inside which the nozzle outer cylinder 1 is movably held, and between both sides of the outer cylinder holding plate, an elastic member 2-1 composed of a support spring is engaged. It is erected at a position rotated 90 degrees with the dowel pin 2-2, a small motor 4 for rotating the cam roller 3 is installed at the tip, and the rear side is fixed to a sanitary washing device (not shown). . Reference numeral 7 denotes a hollow nozzle pipe, which has a jet port 7a for jetting washing water at the upper end of the nozzle pipe, and a rear part which is housed in the nozzle outer cylinder 1 so as to be able to move forward and backward, and a water supply source via a water supply valve (not shown). Is in communication with.

Next, the operation of this embodiment will be described.

A hand switch (not shown) such as a remote controller advances the nozzle outer cylinder 1 from a storage position to a predetermined cleaning position by an advancing / retreating drive motor (not shown), opens a water supply valve, and activates a small motor 4. When the cam roller 3 is rotationally driven, the engagement pin 2-2 of the nozzle outer cylinder 1 swings back and forth and left and right following the meandering groove 3b of the cam roller 3. The elastic member 2-1 installed between the outer cylinder holding plate 5 and the nozzle outer cylinder 1 is elastically displaced in association with the engagement pin 2-2 of the nozzle outer cylinder 1. Therefore, the nozzle outer cylinder 1 swings about the cam roller 3 as a fulcrum, and the nozzle pipe 7 swings as shown by arrows C-D (horizontal movement) and AB (back-and-forth movement) shown in FIGS. The spouting position of the washing water spouted from 7a moves to the left and right, and the front and back moves in a wide range of a size.

Therefore, it is possible to change the jet direction of the washing water in a wide range according to the body shape of the human body to be used, and because of the simple mechanism, the number of motors used is reduced by one compared with the conventional one.

[0013]

[Effect of device]

 According to the present invention as described above, when the cam roller around which the meandering groove for rocking meandering in the front, rear, left and right directions is driven to rotate, the engaging pin of the nozzle outer cylinder engaged with the meandering groove follows the meandering groove of the cam roller. Swing back and forth and left and right. For this reason, the nozzle outer cylinder moves around the cam roller as a fulcrum, and the nozzle pipe oscillates back and forth and left and right accordingly. be able to.

For this reason, comfortable cleaning is possible, and since the number of motors used is one less than in the past and the mechanism is simple, it is possible to provide an inexpensive nozzle swinging device for a sanitary cleaning device.
